The U.S. has numerous goals for transportation in the following general areas: safety, mobility, economic growth and trade, human and natural environment, and national security. Logically a “best practice” policy would contribute to all of these goals, and would have well-accepted monetized costs and benefits that are compelling. However, because of limits to the prioritization of different goals and disagreements about the monetization of some impacts, the identification of “best practice” transportation policies is, and will likely remain, controversial. It may be more practical to consider “relevant” policies, examples of which in the U.S. include fuel economy standards, support for vehicle technology development, tax incentives for efficient vehicles and alternative fuels, and financial support for transit systems, carpools, and vanpools. Related to policies and measures, at least two somewhat fundamental questions also warrant consideration: First, to what extent should transportation sector emissions be managed separately from those of other sectors? Second, to what extent should governments be involved in the selection of ultimate means of reducing or offsetting transportation sector emissions?
